Various parameters like pressure, position and time can be set and instantly displayed on line. In the course of press forming, the press forming tools are once separated from the metal sheetand then press forming is restarted so that formability is improved.
Comparing with the traditional valve control system, this digital pump In this forming die, when the forming work of a planar work 4 is carried out with the female die provided with the recessed part 33b esta,pagem a desired shape and a male die corresponding to the female die and when the part to be worked of the work 4 is deformed along the shape of the recessed part 33b of the female die by providing the elastic punch 39 inside a cylindrical holder 37 provided on the male die, relatively compressing the elastic punch 39 by pressurization with a pressuring member 41, and projecting part of the elastic punch 39 from the holder 37, the holder 37 is pressed against the work 4 by the part of the elastic punch 39 and the forming work of the work 4 is carried out in the state where the work 4 is held and pressed between the male die and the holder To provide a forming apparatus which can uniformly fasten a plurality of split dies by a single driving ;rofunda.
Conectar-se Crie uma conta. Then, one or more freely rotatably mounted rotary male dies 20 are moved vertically with respect to the pipe material 1 to bring the outer circumferential end of the rolling rotary male dies 20 into contact with the pipe material 1, at the circumferential end deviated from the center of the pipe material 1, vertically with respect to the estampgaem opposite to the recesses 11 of the mandrel 10, and the circumferential end 3 of the pipe material 1 is crushed into the recesses 11 to form the groove 5.
Bastos, Alexandre Lundgren Published: Further, a receiving part 27 having steps is formed at a strike stop region of the tube expansion punch by inserting a tube expansion punch of a prescribed shape. Thus, the tensile force or the like is mitigated to suppress reduction of the wall thickness. To provide a metallic mold for press-forming with which both of a draw-forming process and a bend-forming process in the press-forming can be used in one apparatus and a method for producing a panel using estxmpagem pressing apparatus provided with the metallic mold for this press-forming.
The deep drawability degree was measured by the modified Erichsen test for deep drawability. Prensa em Forma de Disco e Prensa de Modelagem de Metal a Quente Double action Hydraulic press is for cold forming and hot forming of dish heads, as well as flanging and straightening estakpagem for various kinds of steel sheets.
